Hi guys,
I don't exactly know which trims you are talking about but if they are the one at the bottom (exterior chrome window trims) of every windows then I might have the answer. Go to an import junkyard (call first b4 you come to make sure they have the model that you need) to purchase the parts. To replace them, roll the windows down then pry from the left to right, from one clip to the other. (look for the clips and pry from the inside of the car where the door panel is) Watch for the glass.
have fun,
